The Organization for Security and Cooperation in Europe (OSCE) comprises 57 participating states, including almost all the countries of the Western Balkans. The only country which is not a participating state of the OSCE in this region is the Republic of Kosovo. Kosovo announced its independence from Serbia on 17 February 2008, and a number of OSCE participating states soon after recognized its statehood. However, some participating states, including Serbia, Russia, Spain, Slovakia, Romania, Cyprus, and Greece, did not. International organizations, such as the United Nations (UN), the European Union (EU), and the OSCE, have been engaged in post-conflict reconstruction of Kosovo since 1999. The aim of this article is to show the role of international community engagement in rebuilding the social security system in Kosovo since the end of the war of 1999. This analysis will enable the reader to understand not only the evolution of the social security system in Kosovo, but also the direct and indirect impact of international community on the social security of the states with limited recognition.
